Abstract: An apparatus for draining cerebrospinal fluid from the ventricle of a brain includes an inner rigid tube and an outer flexible, elastic tube. The proximal end of the flexible tube has perforations to admit fluid into the elastic tube lumen in which the fluid is conducted to the distal end where the fluid exits into the remainder of a drain system, such as a ventriculoperitoneal shunt. The rigid tube contains an elbow bend intermediate the ends. In one form of the apparatus, the rigid tube has a first tubing nipple near one end and a second nipple intermediate the first nipple and the elbow bend. The first nipple extends outside and beyond the distal end of the flexible tube. The second nipple can be used to fasten the flexible tube to the rigid tube. The fastening method can employ a circumferential ligature as with suture thread or with a novel non-elastically deformable sleeve type of compression fitting.
